Submerged or not they are 4 year old neglected west marine batteries. They are good for a core exchange for new batteries.

You can pressure wash the interior of a trailer sailor -- I did it last year to my Catalina 22. Took everything out I could, and hit it with the foam cannon attachment. Then some elbow grease on the stubborn spots. Once it was decent, I went to town with the pressure washer (within reason). Cleaned my "bilge" and everything else. Of course it was in my yard and I had 2 pumps placed in strategic spots to help empty the water. Then a lot of drying with everything open, and a fan helping to move air through the boat. Not ideal, but it was getting to the point where it really needed a good deep clean.
Ok.... So i did and still in the process, got all the water out hatches and everything open so it dries faster, I've been cleaning all that mold by hand with sponge, water and lysol anti mold. Its been slow progress but progress nonetheless. By Friday ill be done with all the cleaning.
